Hire the Best Shopify Developers
in the Netherlands

Netherlands-based Shopify and Next.js developer. I build Shopify stores and custom React / Next.js web apps for European e-commerce brands. One developer, from start to finish: no agency, no handoffs, no "that's the other team's problem." Most Shopify stores are a theme dragged into place and patched until something breaks. Mine are built in code, from the theme up. Recent work: • Shoebill Koffie: a live Dutch specialty-coffee store on Shopify. Recurring coffee subscriptions built on Shopify's own selling-plan APIs, so the client pays zero monthly app fees. Variant catalog (roast, grind, weight), weight-based free-shipping and minimum-order rules, fully localized in Dutch. • Plants by Frank: a custom Shopify store for an organic garden-plant nursery that sells direct to consumers. A deep, filterable catalog organized by plant type, light and use (full sun, drought-tolerant, evergreen, edible), variant-driven products with per-set and per-unit pricing across pot sizes. • Motiv: a B2B SaaS for server-side conversion attribution that measures true ROAS across Google, Meta and TikTok, independent of each platform's own reporting. I built the Next.js and React front-end on Vercel: the marketing site plus the interface of the authenticated app. • HiLeads: a fast, animated Next.js lead-generation site with a live data-visualization dashboard. I still build WooCommerce and WordPress when it's genuinely the right tool, and I migrate stores off it to Shopify when it isn't. What I do: • Custom Shopify store design and build (real custom themes for e-commerce stores, not a theme install) • Native Shopify subscriptions (Shopify's built-in selling plans, no third-party app fee) • WooCommerce to Shopify migration • Next.js and React websites, landing pages and web apps • Dutch and EU checkout: iDEAL, VAT rules, GDPR • Handoff and post-launch support, so you own the code and the store on day one The stack: Shopify (Liquid, custom themes), Next.js, React, TypeScript, Tailwind, Node.js, headless CMS, and the infrastructure to run it (nginx, CI/CD, TLS, monitoring). How I work: I name the stack and the standards up front, then build in the open. Fixed-scope packages with a clear price, feedback rounds built in, and 30 to 90 days of support after launch depending on scope. No disappearing act once the invoice clears. I work in English (near-native) and Dutch (native), so if you're selling into the NL/EU market, your store actually reads right in Dutch, not machine-translated. (I also speak Georgian.) If you have a Shopify store to build, a WooCommerce shop to move, or a Next.js site or web app that needs building right the first time, send me a message with a couple of lines about your project and I'll tell you honestly whether I'm the right fit.

Over the past three years, I've focused on bringing my e-commerce and front-end expertise to the Shopify platform, helping businesses create scalable, custom solutions that drive results. In addition to my core development skills, I have hands-on experience with: - Implementing complex APIs, including third-party integrations and custom middleware solutions. - AI integrations, such as using OpenAI or other machine learning APIs to build smart features. - Automations that streamline workflows and save clients hours of manual work - from marketing flows to internal process automation. If you're looking for someone who can bridge clean UI/UX with powerful back-end logic and smart integrations, I’d love to hear about your project.

Some business need their Shopify or WooCommerce store built right the very first time. While others have one that is grown fast and now orders are not syncing, inventory is off, or integrations are quietly failing. Some businesses want to improve their existing systems. Others are ready to use AI automation to save time and work more efficiently. No matter where you are in that journey, I can help. I am Jeroen, founder of Brightness Group in Amsterdam.
